Patterns of vegetation change in grasslands, shrublands, and woodlands of southwest Oregon ; CSNM livestock impacts study
I 53.2:C 26 /Final ; 34 ; Original print copy at SOU bound in Cascade-Siskiyou National Monument livestock impacts study.; Includes ill. (some col.) and map.; Includes bibliographical references. ; "Little information exists about vegetation change over time in the grasslands, shrublands, and woodlands of southwest Oregon. Multi-aged oak stands, encroachment of shade-tolerant conifers into non-conifer vegetation, reduced reproduction by pine, and the loss of meadows support the generally accepted belief that fire suppression has negatively impacted historically open vegetation types. However, a collation of historic anecdotes, General Land Office (GLO) survey records, homestead patent applications, original and repeat photographs, and other historic information on the general dynamics among oak, chaparral, grassland, and conifer vegetation in this area indicate a more diverse pattern of vegetation change only partially explained by fire exclusion. The historic and continued persistence of some meadows and savanna without recent fire are counter to general assumptions about the loss of open (i.e. herbaceous dominated) plant community structures as a result of fire-suppression.Coarse vegetation reconstructions derived from General Land Office Surveys indicate that oak woodlands were far more common than oak savanna at the time of Euro-American settlement."
